Responsibilities
We are seeking a Senior Frontend Software Engineer to drive the delivery of large, complex UI features, lead architecture and design improvements, and mentor engineers across the team. Working as a senior technical contributor, this role focuses on advancing modern front-end technologies, design systems, and user-centered engineering while contributing significantly to technical strategy. You will have the opportunity to lead major UI initiatives, promote scalable architecture and accessibility, and elevate engineering best practices across the organization.
The ideal candidate is a seasoned engineer (7+ years) who understands that front-end architecture is the bridge between technical feasibility and exceptional user experience. This position will lead complex UI initiatives, mitigate technical debt, and ensure our front-end ecosystem is performant, accessible, and built for long-term scalability.
Essential Responsibilities
Lead the implementation of large-scale frontend features with minimal oversight
Design reusable architecture patterns and contribute to the evolution of shared tooling and design systems
Identify and resolve performance bottlenecks and accessibility issues at a systemic level
Serve as a mentor to associate and mid-level engineers, providing technical guidance, code review feedback, and pair programming support
Collaborate with cross-functional partners and design teams to clarify ambiguous requirements and align UI implementation with product strategy
Influence roadmap priorities through technical feasibility insights and proactive risk mitigation
